1992 King Quad 300 I think it might be the clutch?

The engine is running great but it only gets up to about 15 Mph in high gear, it also doesn't pull like it use to. I don't know much about the semi manual clutch so I am looking for a starting point. So far I adjusted the clutch but I'm not sure if it's tight enough. Any help would be great.

Here  is a copy  and paste  of a response in  another,  Suzuki specific,  forum.  You  may  have actually   loosened the  clutch  if you  screwed the   adjuster in rather than  out.

I hope AJ doesn't mind me using his picture for this because I borrowed it. I can't remember off the top of my head what size bolt that is, I think 17mm, but you remove that bolt and inside you will find a set screw with lock nut, which I think is a 12 or 13mm, Leave your transmission in first gear and go ahead and break the lock nut loose. I would go ahead and use the Phillips screw driver and completely remove the set screw and lock nut. You will not mess anything up doing this. Now after you remove it take the lock nut off of the set screw this will ensure that they both move freely and will make it easier to adjust. Once you have separated them go ahead and put the lock nut back on the set screw just a few threads and reinsert the assembly back into the hole only using your fingers tighten the set screw where you barely feel it touch the plates inside of the clutch. Now while holding the set screw with the screw driver use your fingers and snug the lock nut up. now double check the set screw and make sure it is just barely snug against the plates inside still and loosen it about an eighth of a turn and use a wrench to slightly tighten the lock nut against the set screw, once you are sure that they are somewhat locked together take a socket and snug it up really well to make sure it isn't gonna loosen up on you. Now replace the cover nut and try it out and see if it does the same thing or if it fixed it.

Is it counterclockwise to make the clutch grab faster?

[davefrombc]

From  what I read in that post,  yes.  Back  it  off to  allow the  clutch  to  grab and hold.  The  screw   should  not be touching the  clutch  but should be  within  a  couple of  mm  from it. I  can  only repeat what I read there since I do  not  own  a  Suzuki.. Hopefully  a  Suzuki owner  will  chime  in  to  confirm  or  deny  those instructions.

I backed the screw out some and it's made it a little better but not perfect. I will take it out more tomorrow.

you're not stuck in low are you?

[skyhawk1755]

Not stuck in low. I only get into 2nd gear.

[Grizzlebee]

ahhhhh. it's not a stuck brake is it?

[skyhawk1755]

I know it's not the back one but I didn't check the fronts. I will have to check that.
